[GUTSY] SiS 190 onboard NIC problems

Hi!
Thanks for the bugreport!
I think we can confirm this bug and the workaround working ([1] [2]).
Now as a quick fix, i don't know if there is per-driver scripts in network scripts so that we can change the MTU...
The bug itself would be interesting to investigate... The only probable reference to your problem i have found in the kernel ML [3] didn't seem to get a solution.
Regards,

Hi!

In our computer lab, I have installed edubuntu 7.10 on 13 machines
with Foxconn motherboard 622MX.
This motherboard uses the same network controller and I had the same
problem which I fixed by changing the mtu to 1492.

However, I would like to report that three out of 13 machines were still
facing network connectivity problems.

More precisely, despite the modified mtu, these machines after a cold boot,
were not able to browse web-pages despite that ping-ing a site was working.

For example ping www.google.com was working, while ssh or web browsing
was not working.

Now rebooting to Windows and then rebooting back to Linux was fixing the problem.
Ssh and web-browsing was ok.
However if turned off and then booting to linux, the problem persisted.

It seems that the MTU-work around is not working all the times.

Thank you very much for your support.

I think you should try different values of MTU around and below 1500, also open an Ethereal (wireshark? can't remember its new name) and try to check what is going on with your packets. As this is a computer lab and you probably must fix it, (I don't know if this NIC is so badly designed or is so badly supported by linux drivers), in case you don't manage to fix it you could always buy some cheap network cards around 8-12 euros each, which have a common chip and well supported.

I am assigning this bug to the 'ubuntu-kernel-team' per their bug policy. For future reference you can learn more about their bug policy at https://wiki.ubuntu.com/KernelTeamBugPolicies .

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

This bug report is being closed because we received no response to the previous inquiry for information. Please reopen if this is still an issue in the current Ubuntu release, Jaunty Jackalope 9.04 - http://www.ubuntu.com/getubuntu/download. To reopen the bug, click on the current status under the Status column and change the status back to "New". Thanks.
